# RTC_Init

## C Specification

      #include <nitro/rtc.h>
      void RTC_Init( void );

## Description

This initializes the real time clock API. Call this function before calling any real time clock functions.

## Cautions

Real time clock settings are protected by a battery backup. The initialize function does not initialize settings that are backed up; such as date and time data, hour notation format, alarm parameters, and the like. Therefore, status that is set by other applications will become the initial status, which could lead to unintended behavior.

Applications should not alter the date and time. However, if required, use the application to reset the initial values for hour notation format and alarm settings.

## Arguments
